belng distilled.

necessary, as it would accomplish nothing coked, any gaseous components thereof more than that obtained by the retort 1 being driven off and consumed during the of 111" present construction. The gases distillerf from the oil, together with the superheated steam through the are es and holes through the refractory material therein, and by the heat of said refractory material and arches become converted into fixed combustible gpses, then passing down by the pipe 16 to t e seal 17.

By injecting the oil which is to be converted into gas underneath the refractory material instead of on the top thereof, as heretofore, it is insured that the refractory material will not be in direct contact with the oil but only with the vapor arising therefrom, which vapor will have been raised to a sufficiently high temperature not to materially damage the refractory material by causing too rapid shrinkage thereof; Hence said refractory material will last much longer than heretofore, Again there will now be no deposition of coke or other carbonaceous material upon the refractory material, but what is formed will. fall to the bottom of the retort, the volatile portions lhcrcfore,'uponcommencing the step of heating up, no carbon will be driven off unconsumed in the form of smoke through the stack, Also this coke falling to the bottom can be scraped out from time to time through a door 18. The solid hydrocarbon will have been perfectly l l l l ass into the first chamber step of heating the refractory material.

If it is desired, to increase the quantity of coke produced, it is only necessary to increase the amount of oil fed into the retort chamber. Or, if desired, coal may be fed into said chamber through the door 18.

I claim The process of making as and coke which consists in simultaneous y highly heating two segregated bodies of loosely piled refractory material and a retort chamber, dis-v continuing the step of heating, passing steam into contact with one body of refractory: material to superheat the steam, passing oil directly into the retort chamber to distil the oil, retaining the non-volatile components of the oil in said chamber in the form of coke, and passing only the steam so superheated and. the volatile portion of the oil so distilled together into contact with the second body of refractory material, to make combustible gases, substantially as described.

In Witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.
